Data from "American Narrow-Gauge Works Locomotive", Locomotive Magazine, Volume 23 (15 February 1917), pp.21-22. Works numbers were 6063 in January 1918 and 6064 in February. (Given the date of the LM report, the building dates shown above don't seem possible. Yet all sources available to Locobase give January & February 2018.)
Pittsburgh-based Carnegie Steel bought many small industrial locomotives from Pittsburgh-based H K Porter. They ran on several gauges of which the 30" (762 mm) was the narrowest. LM's report on this order claimed that it was "probably the most important that has been constructed for such a narrow gauge ...We cannot call to mind any other engine weighing 43 tons carried on four wheels."
